從構(gòu)造上清除了法蘭盤四邊的透風(fēng)安全隱患。根據(jù)在法蘭盤四周選用新式橡膠密封件而且在各邊選用延展性法蘭盤夾或選用實(shí)際效果更強(qiáng)的頂絲卡，均使風(fēng)管管道密封性實(shí)際效果更為靠譜，經(jīng)工程項(xiàng)目具體檢驗(yàn)，透風(fēng)成交量放大角鐵活套法蘭小1/3上下;
The hidden danger of ventilation on the four sides of flange plate is removed from the structure. According to the selection of new rubber seals around the flange plate and the selection of malleable flange clamp or top screw clip with stronger actual effect on each side, the actual sealing effect of air duct is more reliable. According to the specific inspection of the project, the ventilation volume is enlarged by 1 / 3 of the angle iron looper;
簡(jiǎn)單化了角鐵(鍍鋅扁鋼)法蘭盤繁雜的制作工藝，非常是去除開在其中很多的手工制作工作，濟(jì)南通風(fēng)管道顯著地提升了工程施工率。實(shí)踐經(jīng)驗(yàn)，選用共板活套法蘭，每一插口的制做與安裝，可節(jié)約50%左右綜合工時(shí)。
Simplified the angle iron (galvanized flat steel) flange complex manufacturing process, is very much removed in which a lot of manual production work, Jinan ventilation pipeline significantly improved the efficiency of engineering construction. Practical experience, the selection of common plate looper flange, the manufacture and installation of each socket can save about 50% of comprehensive working hours.
